Abstract

This work is about the possibility of early diagnostics of the technical condition of the main reduction gear in the helicopter. Tribological tests of oil samples taken when testing the operational life are conducted based on the analytical ferrography, morphological analysis, wear particle count, and spectroscopic analysis.
